A fixing belt is installed on the front portion of the upper plane of each armrest in a sliding mode, and handcuffs are fixedly arranged at the upper ends of the fixing belts. Screws are fixedly arranged in the armrests coaxially, slide ways are arranged on the portions, corresponding to the screws, of the outer side faces of the armrests, bevel gears run on the slide ways, the bevel gears are engaged with the screws in the armrests, the bevel gears are installed on the fixing belts, and hand cranks are fixedly arranged on the portions, outside the fixing belts, of the ends of the bevel gears. According to the wheelchair, the handcuffs are installed on the armrests of the wheelchair to control and fix upper limbs of a prisoner, the handcuffs can move on the armrests front and back in the mode that the bevel gears are engaged with the screws, and the prisoner is more effectively controlled; due to the fact that the armrests where the handcuffs are installed are fixed to the pedal frames fixedly arranged on the frame, the whole structure is very stable, and manufacturing is easy.

Description

A kind of handcuffss may move prison wheelchair

The content of the invention

It is an object of the invention to overcome the deficiencies in the prior art part, there is provided a kind of that the upper limb of convict, lower limb can be entered The removable prison wheelchair of handcuffss of row dibit locking.

The technical proposal for solving the technical problem of the invention is：

A kind of handcuffss may move prison wheelchair, the wheelchair include vehicle frame, the chair back, seat support, pushing hands, arm-rest frame, handrail, Pedal frame, pedal, are fixedly mounted with a pushing hands behind the chair back, and both sides are symmetrically installed arm-rest frame in the middle part of the vehicle frame of wheelchair, every Level is fixed with handrail on one arm-rest frame；Pedal frame is symmetrically fixed with vehicle frame front part sides side, in the lower end of each pedal frame Hinge fills a pedal, it is characterised in that：The front portion of plane is slidably installed a fixing band on each handrail, and the fixing band upper end is consolidated Fill a handcuffss；A screw rod is coaxially fixedly mounted with handrail, to a slideway should be formed with the handrail lateral surface of screw rod, in the slideway Upper operation has a bevel gear, and with screw rod in handrail internal messing, the bevel gear is arranged in fixing band bevel gear, and it is outside fixing band Bevel gear end be fixedly mounted with a hand crank.

And, the bottom of the fixing band that the handrail is installed is packed on pedal frame.

And, foot handcuff is fixedly mounted with the vehicle frame below the seat support of wheelchair, the foot handcuff passes through below support bar and seat support Vehicle frame is fixedly mounted with.

The present invention be a little with good effect：

1st, this wheelchair is provided with a handcuffss at wheelchair armrest position, with control and fixed convict upper limb, and using cone tooth Wheel engagement screws mode makes handcuffss to move forward and backward on handrail, more effectively to control convict；Installed due to handcuffss Handrail is integrally fixed on the pedal frame being fixedly mounted with vehicle frame, and total is very firm, and easily fabricated.

2nd, foot handcuff is fixedly mounted with vehicle frame of this wheelchair below seat support, with control and fixed convict lower limb, thus dibit Fixation be preferably minimized can the danger of convict, advantageously reduce danger when bringing a prisoner before the court or shift convict.

3rd, this Wheelchair structure is simple, and design science is skillfully constructed, and can satisfactorily control row of the upper and lower limb of convict on wheelchair It is dynamic, it is to avoid the generation of serious accident, is one of indispensable facility in prison.
